Qwen2.5-Coder-3B-Vitest (GGUF)

A domain-specialized version of Qwen2.5-Coder-3B fine-tuned to generate Vitest + React Testing Library unit tests for React components.

The model focuses on behavior-faithful testing, avoiding hallucinated UI/state and preferring modern RTL best practices.

🔍 What this model does

Generates Vitest tests using React Testing Library.

Prefers:

• getByRole, getByLabelText, getByPlaceholderText
• userEvent for interactions
• vi.fn() for callback assertions

Avoids:

• Hallucinated UI or state
• Testing behavior not present in the component
• Legacy fireEvent

Tries to produce behavior-faithful, minimal tests.

🧠 Training details

Detail	Value
Base model	Qwen2.5-Coder-3B
Method	LoRA fine-tuning using MLX (Apple Silicon)
LoRA rank	16
Trainable parameters	6.6M (0.216% of total)
Dataset	~800 curated React component ↔ Vitest test pairs
Sequence length	2048
Training	3 epochs (450 steps)
Hardware	Apple Silicon (Mac mini M4 Pro, 64 GB RAM)

The dataset was curated and scored to:

• Prefer robust RTL queries
• Penalize async misuse, fireEvent, focused/skipped tests
• Enforce correct callback testing for callback-only components
• Encourage clean, production-style tests

📦 Files in this repo

• qwen2.5-coder-3b-vitest.Q4_K_M.gguf — Quantized GGUF build (recommended for Ollama / llama.cpp)

🚀 Usage with Ollama

Create a Modelfile:

FROM qwen2.5-coder-3b-vitest.Q4_K_M.gguf
TEMPLATE """
You are an expert frontend test engineer.
{{ .Prompt }}
"""
PARAMETER temperature 0.2
PARAMETER top_p 0.9
PARAMETER num_ctx 4096

Then run:

ollama create vitest-coder -f Modelfile
ollama run vitest-coder "Write Vitest tests for this React component: ..."

⚠️ Limitations

• May overuse async/await in simple sync cases
• May generate redundant tests for trivial components
• Best results when provided with clear component context
• For large repos, using RAG (retrieval of similar tests/components) improves quality
